There are two possibilities when the cubic insulin crystal is indexed and only one of them complies with the porcine insulin crystal structure deposited in the PDB as 9ins .
The structure was solved by a difference Fourier method using REFMAC (Murshudov et al. , 1997 ▶ ) in the CCP4 suite (Collaborative Computational Project, Number 4, 1994 ▶ ) with porcine insulin (PDB code 9ins ) as an initial model (Gursky, 1992 ▶ ).

From above discussion it seems plausible that the model that fits these observations could be explained by the help of insulin structure (PDB ID: 9INS)  shown in Figure 5 .
On the right side are the structures exhibiting the surface potential on the insulin molecule (blue - positive; red – negative, these structures were obtained by running PDB2PQR version 1.7  on 9INS followed by processing with APBS software  ).
